Lisalisa, my 14 mth old dd has never napped very well during the day, maybe 30 mins in the morning and another 30 mins in the afternoon if I'm lucky.
Unfortunately she doesn't sleep well at night either!
Last night she was awake for nearly 2 hours 4am -5.30 am, then went back to sleep until 7.30am, but has still only had 45 mins sleep today...
I worry frantically about her daytime naps, as I find it hard to stick to a solid routine as I also have a 3year old to contend with. She also won't sleep in her cot in the daytime, only in the car or buggy.
I sympathise with you completely. Many people tell me to chill out about her naps, but it's hard when you have a fractious, tired toddler on your hands.
I guess it may just be a phase your dd is going through? I would try and ride with it and maybe it will pass. I can't offer much other advice, only my empathy... it's hard work isn't it?? I despair sometimes!!!
